BACtrack Z9 Enforce (BT-Z9-EN) Product Manual TABLE OF CONTENTS This device is intended to measure alcohol in human breath. Measurements obtained by this device are used in the diagnosis of alcohol intoxication. Introduction Operation Precautions Calibration Accessing Regulatory Information Warranty Service INTRODUCTION The BACtrack® is an alcohol screening device, used for the detection of alcohol in the breath. The BACtrack provides a digital result indicating the approximate BAC (Blood Alcohol Content) of the test subject. The BACtrack is easy to use; simply turn on the unit and begin testing in a matter of seconds. Before you begin testing, please read this manual in its entirety and familiarize yourself with the BACtrack. Your Breathalyzer is powered by a battery that can be recharged via the USB-C cable provided. Simply use the cord to plug the unit into a USB slot and the charging will begin. ALCOHOL AND ITS EFFECTS ON THE HUMAN BODY Alcohol is absorbed from the mouth, throat, stomach, and intestines into the bloodstream. Alcohol ingested by the human body can be detected in the breath because of its presence in the bloodstream. Alcohol cannot be digested and it cannot be chemically changed in the bloodstream. As the blood flows through the lungs, alcohol in the bloodstream moves across the membranes of the lung's air sacs (alveoli) into the air. The concentration of the alcohol in the alveolar air is directly related to the concentration of the alcohol in the blood. As the alveolar air is exhaled, the alcohol in it can be detected by the breath alcohol testing device. The alcohol concentration in the breath is related to that in the blood, and because of this, an individual's BAC can be determined by measuring alcohol in the breath. The ratio of breath alcohol to blood alcohol is generally estimated to be 2,100:1. Therefore, 2,100 milliliters (ml) of alveolar air will contain approximately the same amount of alcohol as 1 ml of blood. ALCOHOL IS A DRUG Alcohol is the chemical (ethanol or ethyl alcohol) resulting from the fermentation of grapes or grain. Alcohol is absorbed directly into your bloodstream. From your bloodstream, the fluids in your body tissues absorb the alcohol. Your brain is made up of a large concentration of fluids and will absorb a large amount of any alcohol you drink. Your liver eliminates the absorbed alcohol at its own rate of time and nothing you eat or drink can speed up the process. Your liver does this by oxidizing the alcohol (converting it into water and carbon dioxide). Coffee, food or any other "cure" will not sober you up; only time will do that. HOW DOES ALCOHOL AFFECT MY BODY? Alcohol is a depressant. It has a relaxing effect on the muscles in your body. The muscles of your eyes relax and lose focus. Your eyesight will become fuzzy and you may experience double vision. Brain activity is slowed. Your judgment, reflexes, and coordination are all negatively affected. Some vision impairments that occur when you have been drinking include: ● Narrowing of your field of vision ● Reduction in your depth perception ● Decreased ability to see in darkness ● Increased sensitivity to glare and a longer time for your eyes to readjust from the glare Some mental impairment can occur when you have been drinking, including: ● Reduced awareness of danger Becoming overly confident and reckless ● Difficulty in making decisions ● Reduction in balance ● Slowed reflexes ● Impaired judgment HOW DOES ALCOHOL AFFECT MY DRIVING? We can't emphasize enough how dangerous it is for you to drink and drive. Your vision and your brain are the most important factors in driving safely. If you jeopardize either by drinking, and then you drive, you are likely to be involved in a serious or fatal collision. Do not use your BACtrack as a tool to determine whether you should operate a motor vehicle or equipment, or perform any other dangerous act. Do not drink and drive. Always have a designated driver when alcohol is being consumed. From California Department of Motor Vehicles (http:ltwww.dmv.ca.gov COMPONENTS DIAGRAM OPERATION Press the Power Button on your BACtrack for one second to turn on the device. Your BACtrack will display “Warming Up” When the BACtrack displays READY, inhale a deep breath and blow steadily and consistently for six seconds through the mouthpiece. Stop blowing when the beeping sound stops. There is a click at the end - that’s the air pump pulling air across the sensor. Once the sensor has analyzed the breath sample, the estimated BAC value is displayed. SPECIFICATIONS DIMENSIONS 89.5 x 71 x 16 mm WEIGHT 0.09 kg DETECTION RANGE 0.000 – 0.400 %BAC POWER SUPPLY Lithium-ion Battery OPERATING TEMPERATURE 32-104 °F (0-40 °C) VOLTAGE: 5V USB charging at 500mA maximum current PRECAUTIONS ● Wait at least 20 minutes after drinking, eating or smoking before testing. Not observing this waiting period can cause inaccurate readings and damage the sensor. ● Do not blow smoke, food, or liquids into the BACtrack because this will damage the sensor. ● Do not test in areas with strong winds, smoke, or in an area where a large amount of alcohol is being consumed. ● Avoid testing in the presence of any substances that contain methyl alcohol, isopropyl alcohol or acetone. These substances may interfere with the results of the test. ● Send your tester in for periodic calibration service as required. (See Calibration). ● The BACtrack Breathalyzer is designed to be used in a temperature range of 32-104 °F (0-40 °C). ● You cannot use the results of this product in court ● Do not use the BACtrack as a tool to determine whether you should operate a motor vehicle or equipment, or perform any other dangerous act. ● Do not drink and drive. Always have a designated driver when alcohol is being consumed. CALIBRATION All BACtrack products are calibrated during the manufacturing process and should remain accurate for 6 to 12 months depending on the number of tests performed and operating condition…

To simulate free space, the ground plane was covered with RF absorbing cones. The reference antenna and EUT were placed on a block of approximately 1.8 m low permittivity foam. A signal generator was connected to the reference antenna with a low loss RF cable. To minimize the influence of the RF cable in the radiating pattern, the cable was lined with snap on ferrites at a separating distance of 10 cm. A CW tone was then provided to the calibrated reference antenna and reference scan was then collected at the frequencies noted in this test report. Using the same test setup, the antenna under test (AUT) was placed into the chamber. If an RF patch cable was provided by the manufacturer an additional offset factored into the final value. A polar plot was then collected at the antenna height of maximum field strength. This plot was then compare…
